DC Voltage Detector Operation Manual
Mode #: DCDTC
This Sigineer Power’s DC Voltage Detector is designed with 3 relays which will close or open at preset battery voltage to trigger the operation of Inverter Charger RLCD, 60/62.5hz inverter frequency switch and AC circuit breaker with remote control.
All the 3 relays are rated at 2 amps and operate within designed amp/voltage.
On the top cover, there are three buttons: “Set””Up”and ”Down”.
On the side, there is a 2-pin DIP switch, the nominal battery voltage is set through DIP switches , 0,0 for 12v / 1,0 for 24v / 1,1 for 48v
The voltage setting comes in increments of 0.1Vdc.
| Detector Setting | Relay Status | Connection | 12V | 24V | 48V |
|---|---|---|---|---|---|
| 1 Low Battery Cutoff | Relay A gets from Close to Open | Dry Contact on RLCD | 6-17v | 13-34V | 26-68V |
| 2 Low Battery Recovery | Relay A gets from Open to Close | Dry Contact on RLCD | 7-18V | 14-35V | 28-70v |
| 3 Frequency Switch | Relay B gets from Open to Close | 60/62.5hz Dry Contact | 7-18V | 14-35V | 28-70V |
| 4 Frequency Recovery | Relay B gets from Close to Open | 60/62.5hz Dry Contact | 6-17V | 13-34V | 26-68V |
| 5 AC Charger Cutoff | Relay C gets from Close to Open | Remote Control of AC Input Breaker | 7-18V | 14-35V | 28-70V |
| 6 AC Charger Recovery | Relay C gets from Open to Close | Remote Control of AC Input Breaker | 6-17V | 13-34V | 26-68V |
| 7 Screen Timeout | 10 to 60 mins, 99 represents constant on | ||||
| 8 Audio Alarm | 99 represents constant on, 00 presents off |
| Relay | Wire Color | Statue | Function |
|---|---|---|---|
| A | Blue+Green | Constantly Close | Connects to dry contact at Inverter Remote LCD, gets open at preset voltage to power off inverter. |
| B | Yellow+Orange | Constantly Open | Connects to 60/62.2hz frequency switch dry contact, get closed at preset voltage to change frequency to 62.5Hz. |
| C | Black+White | Constantly Close | Connects to circuit breaker remote control cables, opens at preset voltage to cut off AC input for charging. |
| C | Black+Red | Constantly Open | Reserved for users. |
Note:
1: The low battery alarm is 0.5V higher than “1 Low Battery Cutoff” at 12Vdc, 1Vdc at 24Vdc and 2Vdc at 48Vdc.
The high voltage alarm is 0.5V lower than “5 AC Charger Cutoff”, at 12Vdc, 1Vdc at 24Vdc and 2Vdc at 48Vdc.
The audio alarm is controlled by setting “1” and “5” only.
2: Setting 3 is lower than setting 5 in software. There is a locking between 1&2, 3&4, 5&6. Setting 2 is 1V lower than 1. Setting 3 is 1V higher than 4. Setting 5 is 1V higher than 6.
3: Low voltage alarm, beeps 0.5s at every 5 seconds; high voltage alarm, beeps 0.5s at every 2 seconds;
4: Setting 7(Screen Timeout) is for LED light time, resettable value from 10, 20, 30, 40, 50, 60 minutes to 99 which represent constantly light.
5: For relay C, there are three cables, white, black and red, the users can choose to two of them to flexibly control our circuit breaker.
